Investigations were realized under two different environmental conditions in the Central Europe (Czech Republic, SW Bohemia): (i) ?normal? cold winter (average temperatures = from - 0,8 to - 0,12\u00B0C (November ? March) in the center of South Bohemia; waters were covered by ice and snow from December to February), and (ii) unusual ?mild? winter (average temperature = + 4,8\u00B0C; waters without ice cover). The overvintering mode depends on the winter temperatures and weather ending into presence or absence of ice and snow-cover of waters. Corixids can overwinter in groups formed by tens or hundreds specimens, actively or inactively on the bottom in the normal winters if the water surface is covered by ice and snow. Assemblages sampled in normal winters are poorer in comparison with both summer taxocenoses and assemblages sampled during a mild winter.
